Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..
2+2 = 2*2 = 2^2 all simplify to 4. But there is no special name for the three expressions.
Yes, you can but it depends on the context. You can simplify fractions, or simplify surds, or algebraic expressions and in each case the simplification means different things. So if you want a sensible answer to your question I would suggest that you use a proper question rather than stick a quastion mark at the end of a phrase!
simplify
Most scientific calculators don't have the capacity to simplify mathematical expressions, only to calculate based on known numbers. For calculating powers, there should be a key labelled something like xy or yx.
They are used to simplify expressions by helping to reduce the numbers that there is
Yes. Expressions cannot be expressed without variables. There are numerical expressions for ex. 2 + 3 is an expression without variables.
To evaluate a variable expression, replace all the variables with numbers and simplify the resulting numerical expression. 3m for m = 9 3(9)=27
you use a mathematical formula ...

Basically the same way that you evaluate other types of expressions with variables: * You replace the variables by the value assigned to the variables. * Then you do the specified calculations.

There are several things you can do to simplify expressions. Specifically for expressions with several terms, two things you can do is to combine similar terms (terms that have the same combination of variables), and then (usually after combining), see if you can apply one of the common methods of factoring, such as looking for common factors, looking for a perfect cube, factoring the difference of squares, the sum or difference of cubes, etc.
Learn the properties, and apply them! What properties you use depends on the specific situations; some examples include:* Combine like terms (terms with the same variables), e.g.: 4x + 5x = 9x * Factor expressions * Multiply factors, so you can combine them with other expressions. In a way, this is the opposite of the previous point.
Use the trigonometric relations and identities.
